A simple yet powerful trick to quickly get the answer:
Many a times when we are in market buying vegetables, fruits etc or buying tickets we use 100 or 1000 rupee notes. This type of maths is useful.
ðļ When we want to deduct any sum from figures like
10, 100, 1000, 10000 etc this trick is useful ðļ
Examples :-
1. We want to deduct 674 from 1000....what will you do?
For this deduct first figure from 9 and the last figure from 10. So the answer is...
9 - 6 = 3
9 - 7 = 2
10 - 4 = 6
Your answer : 326
2. 10000 - 4328 = ?
As said earlier..
9 - 4 = 5
9 - 3 = 6
9 - 2 = 7
10 - 8 = 2
Answer is 5672.
3. 100000 - 66758 = ?
9 - 6 = 3
9 - 6 = 3
9 - 7 = 2
9 - 5 = 4
10 - 8 = 2
And you get : 33242 !!ððž
